GitHub Outage History

We are investigating reports of impacted performance for some GitHub services.

We have identified a likely cause and are applying a mitigation

We have applied mitigation and are seeing recovery

We are investigating reports of degraded availability for Copilot

We are experiencing degraded availability for chat & agent models in Copilot. Multiple models are impacted and customers may experience requests failing. We are investigating and will provide an update as soon as possible.

We've applied a mitigation to unblock Copilot functionality. Users may start to see signs of recovery. Relaunching your client should accelerate signs of recovery. We will continue to monitor the situation.

We are investigating reports of degraded availability for Copilot AI Model Providers

We are experiencing degraded availability for the Opus 4.8 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

We are investigating reports of impacted performance for some GitHub services.

We are investigating reports of degraded performance for Webhooks

Webhooks delivery latency has returned to normal levels. The backlog that built up during the incident has been cleared at approximately 4:29 UTC. We consider this incident resolved.

We are investigating reports of degraded performance for Webhooks

We are currently experiencing delays in Web Hook delivery and are actively investigating the root cause.

We have applied a mitigation and are monitoring for recovery.

We are investigating reports of degraded performance for Copilot AI Model Providers

We are experiencing degraded availability for the Claude Opus 4.7 model in Copilot products and IDE surfaces. This is due to an issue with an upstream model provider. While we work with them to resolve the issue, we recommend choosing another model or selecting 'Auto' to continue using Copilot.

We are experiencing degraded availability for the Claude Opus 4.7 model in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue, and starting to see recovery.

We are investigating reports of impacted performance for some GitHub services.

Issues is experiencing degraded availability. We are continuing to investigate.

Issues is experiencing degraded performance. We are continuing to investigate.

Pull Requests is experiencing degraded performance. We are continuing to investigate.

Following investigation, we are seeing that impact is limited to unauthenticated users when accessing Pull Requests or Issues. Our team continues to work towards mitigation with more updates to follow as we have them.

Actions is experiencing degraded performance. We are continuing to investigate.

We are investigating reports of impacted performance for some GitHub services.

Packages is experiencing degraded performance. We are continuing to investigate.

We are investigating reports of impacted performance for some GitHub services.

We are conducting routine maintenance on our network infrastructure in the EU. This will not impact production traffic, but may result in slightly increased latency for the remainder of our work. We expect this to last until 15:00 UTC.

We are investigating reports of impacted performance for some GitHub services.

Customers may see unexpected repo unsubscription events in their Slack or Teams channels.

During 14:49 UTC to 16:45 UTC, customers may have experienced authorization failures for legitimate requests. This was caused by a recently enabled feature flag, which has now been turned off as a mitigation. Customers should now see normal authorization behavior. This is also the cause of the chat integration issue, and we are exploring options to restore it. In the meantime, customers can manually re-subscribe their repo.

We are investigating reports of degraded performance for API Requests, Git Operations, Issues and Pull Requests

We're continuing to investigate degraded performance of Git operations, Issues and Pull requests.

We are investigating reports of degraded performance for Actions and Pages

Actions is experiencing degraded availability. We are continuing to investigate.

We are investigating authentication issues leading to failure in starting Actions runs and downloading actions. At this time the majority of Actions runs is impacted.

Actions is experiencing degraded performance. We are continuing to investigate.

We have identified the cause of the authentication issues affecting GitHub Actions and are actively working on mitigation

We are investigating reports of impacted performance for some GitHub services.

We are seeing an increased rate of authentication failures for app installation tokens, affecting approximately 1% of tokens. We are continuing to investigate.

We are continuing to investigate an elevated error rate of authentication failures for app installation tokens. Next update in one hour.

We are seeing signs of mitigation and are continuing to monitor for complete mitigation. Next update in one hour.

We see significant signs of mitigation and are monitoring for full mitigation.

We have identified and are applying additional mitigation and will continue to monitor for complete mitigation.

This is fully mitigated, we will continue to monitor to ensure it does not reoccur.

We are investigating reports of degraded performance for Actions

A subset of runners are taking longer than expected to connect, which may delay some jobs from beginning execution. We are actively working to mitigate the issue.
